Frequently asked questions
How do I know if this battery is compatible with my HP laptop?
The safest way is to check the part number printed on your original battery. If it matches 646656-421 or any of the codes in the 'Compatible Part Numbers' list (such as HSTNN-DB3B or MT06), this battery is the correct one. You can also verify if your laptop model, such as HP Pavilion DM1 or Mini 110, appears in our list of compatible devices.
Do I need to calibrate the battery the first time I use it?
Yes, to calibrate the charge sensor and ensure the operating system displays the correct percentage, we recommend a complete initial cycle. Charge the battery to 100%, let it rest for an hour, then use it until the laptop turns off by itself. Finally, charge it back to 100% without interruptions.
How long will the battery charge last?
Battery life depends on laptop usage (screen brightness, programs, etc.) and power settings. This 4400mAh battery is designed to offer a duration similar to that of the original battery when it was new, providing several hours of work.
What warranty does it have and what do I do if it doesn't work or fit?
We offer a 3-year warranty for individuals (1 year for professionals). If the battery is not compatible or has any defect, you have 14 days to return it. You can manage the return shipment on your own or request a home pickup for 8.90 € in Spain and Portugal, an amount that will be deducted from the refund.
